How can I import my SMS message from a Samsung phone to a Sony one?

New PS Studio gave me a .nef file that I can't import to my Sony phone.

  • I have a new Sony Experia x10, and would like to import my backed-up sms's from my Samsung S4. The Sony PC Companion does not recognise the Samsung files. Samsung has a BK extention and Sony DBK.

Use SMS Backup & Restore assuming those are both Android phones and you shouldn't need to deal with a .nef file.


The .nef file is actually a normal database, which can be opened (and exported, and edited and ...) by Microsoft Access. The only thing is that it has an unrecognizable extension. Rename the file to xxxx.mdb, and you can open it in Microsoft Access by double-clicking it.
